Silk and diamonds aren't just for ties and jewelry anymore. They're ingredients for a new kind of tiny glowing particle that could provide doctors and researchers with a novel technique for biological imaging and drug delivery.

The sponges of the future will do more than clean house. Delivering drugs and trapping gases are all potential applications. That's what chemist Jason Benedict had in mind when he led the design of a new, porous material whose pores change shape in response to ultraviolet light.

A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water, according to research conducted at the Wyss Institute of Biologically Inspired Engineering at Harvard University. Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.

For the first time ever, scientists have managed to move single atoms vertically inside a crystal. This is important for the further development of nanostructures. Simultaneously, the physicists found a method for measuring a transistor-like behaviour of single atoms.

New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics - a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.

Scientists have been able to switch on and off robust ferromagnetism close to room temperature by using low electric fields. Their results are inspiring for future applications in low-power spintronics, for instance in fast, efficient and nonvolatile data storage technologies.

A new study led by engineers at Rensselaer Polytechnic Institute demonstrates, for the first time, a simple method for determining the strength and stiffness of practical samples of the nanomaterial graphene.

Scientists have developed a new, inexpensive material that has the potential to capture and convert solar energy - particularly from the bluer part of the spectrum - much more efficiently than ever before.
